查询词典 boulder train

In order to solve the heavy workload and the low efficiency of the train maneuver, one kind of train security alarm system based on GPS and INS technique was presented. The Kalman filter used in the information fusion of GPS and ISN was analyzed, solving the problem of the infinite position error of an INS and the slow modification rate of a GPS. By using the original train database to correct the mileage, the precision of the system was improved.

为了弥补目前火车车辆运行中人工统计调度工作量大、效率低等缺陷，提出了一种基于全球定位系统和惯性导航技术的火车安全告警系统的设计方案；重点讨论了GPS/INS在信息融合时所使用的卡尔曼滤波方法，避免了独立的惯性导航系统无限位置误差和GPS的1 Hz慢速数据修正的问题；利用原有国家铁路网数据库进行数据修正，进一步提高了系统的精度。

Driver sets mode switch to "OFF", and pulls out master control key; waits for and until the indicator of "train reversal ready" flashes , presses "driverless reversal operation button" on the driver console, or else, leave the train and presses "driverless reversal operation button" on platform; train automatically drives to reversal tracks and backs to departure platform, car doors and platform screening doors are automatically opened, the driver moves into the driver cabin and inserts the key.

司机将模式开关设置为&OFF&位置，拔出主控钥匙；等待&列车折返准备好&指示灯点亮后，按压驾驶台上的&无人自动折返按钮&，或者离开列车，按压站台&无人折返按钮&；。列车自动运行到折返轨并回到发车站台，自动打开车门和站台屏蔽门，驾驶司机进入驾驶室，插入钥匙。

针对旅客列车列流图手工绘制存在的问题，研究开发了旅客列车列流图计算机辅助设计系统，对旅客列车列流图的3个组成部分：铁路路网、列流线和图例的自动描绘，从算法、思路和步骤等方面分别进行了论述。

For a model of mastermind alliance at work,consider a train crew.The conductor can take the train to its destination only because all the other members of the train crew recognize and respect his authority.

让我们先来看一下&火车列车员&的智囊团模式：列车长之所以能够使火车开往目的地的惟一原因，就是其他列车员认同并且尊重列车长的职权。

Today there is a girl on the train lost her train ticket, so the conductor asked her to get off the train.

Lisa：今天车上有个女孩把车票弄丢了，所以列车长要赶她下车。

Under the circumstances of putting new railway lines into use or improving passenger train speed or increasing freight train tonnage or reforming driving system, Train traction test has become one foundational technical job. It provides scientific data for railway administration to make management decision and transportations plan, to dug potential and increase profit.

机车牵引试验是在新建线路投入运营、客运列车提速、货运列车增加牵引吨位、司乘制度改革及机车交路变化等情况下所进行的一项基础性技术工作，为铁路部门经营决策、制定运输方案、挖潜增效提供科学依据。

If can cause the train to surface the boat from the railway rail, eliminated between the train wheel and the railway rail friction, can enhance the train large scale the speed.

果能够使火车从铁轨上浮起来，消除了火车车轮与铁轨之间的摩擦，就能大幅度地提高火车的速度。

The influence of its main design parameters on the floating displacement is analyzed.These provide theoretical background for the design of the basic floating parts of the star gear train.The floating displacement of center gears does not change with the power change of the train,and increases with the increase of the rotational speed of the train...

分析表明，中心轮的浮动位移量不随系统输入功率的变化而变化，随系统转速的增大而增大；中心轮的浮动位移量随系统星轮个数的增加而增大，随系统构件误差值的增大而增大，各构件的误差值对中心轮的浮动位移量的影响有累加作用；中心轮的浮动位移量随其齿轮的质量及转动惯量的增大而增加。

Flying may seem a lot quicker than taking the train but add getting to and from airports (train stations are typically situated in the heart of cities) and those dreaded snakelike airport queues at check-in and security, now ever longer and more soul-destroying, and the train can end up more convenient and timely than the plane.

飞行看起来也许比坐火车快得多，但加上往返机场的时间（火车站一般都位于市中心），以及机场登记处和安检处排起的可怕长龙（现在队伍越来越长，也更折磨人），火车可能最后倒比飞机更便利、更及时。
